The factory bulb is completely tinted orange. This makes the housing it resides it turn orange as well. OLM replacements have much less color in the bulb overall. This makes the color in the housing less noticeable.
Turn signals are obviously important and it takes a high power LED to replace the stock halogen bulb. These lights are bright enough so there are no safety issues with using them.
Bulbs are sold as a PAIR.
These are great lights. I have OLM lights for DRLs, fogs and now my front blinkers. I’ll be getting the rear blinkers soon Definitely a solid buy.
